Cookbooks that have sold over 100,000 copies, regardless of when they were first published, can be submitted for the Walter S. McIlhenny Hall of Fame, honoring books considered classics in the field. To date, sixty books have been honored with this distinction. A copy of each book entered in the competition is placed in the Walter S. McIlhenny Library at the McIlhenny Company headquarters on Avery Island, Louisiana. This collection is available to journalists, cookbook authors, and others interested in researching local culinary customs.
